It seems to be the same problem in this topic AGX Orin 64G(DG4064型号eMMC)版本使用中出现mmc0故障报警导致系统卡死, which mentioned update to jetpack-6.1 can solve this, but I want to know which patch between jetpack-6.0 and jetpack-6.1 can work.

Is this on custom board or NV devkit?

6

Hi wayne

Is custom board

7

Is this issue possible to reproduce on NV devkit? Actually I don’t see anything that fixed on our side regarding to this issue.

8

Hi Wayne

This issue only occurs occasionally, we only have one devkit, have not met this issue.

I tried to reboot devkit repeatedly to reproduce issue, but system corrupted after 3 reboots, see “Repeated reboot at slot A in jetson orin with rootfs A/B=1, but boot to slot B unexpectedly, so sad :(

Dear Waynne：

https://forums.developer.nvidia.com/t/mmc0-error-cause-system-to-freeze/349780

这个客人在自己的板子上遇到的情况，是否可以给些建议，比如需要再提供什么信息，或者可以做哪些test？

盼回复，谢谢！

Hi,
We would suggest upgrade to latest Jetpack 6.2.1 r36.4.4, to have latest software for Orin series.
